EGR stuck open. But before you buy an EGR valve check all connections to it. May be off or loose.

Does the Grand Am feature a vacuum operated EGR or is it a servo operated one?

I always assume vacuum and always insist they replace the butyl rubber with silicone vacuum lines....the way every BMW comes off the assembly line~
